The blower may include: an air suction port for sucking external air; a wind generating unit 44 (fig. 6) for generating wind from the sucked air and heating the wind; and a ventilation opening 58 (fig. 6) for flowing the wind generated by the wind generator forward.
The wind speed changing device 10 of the present embodiment is incorporated as a separate device at the front end of the ventilation opening of the hair dryer, or may be disposed inside the ventilation opening of the hair dryer.
In the present embodiment, the description will be made centering on the air velocity converter 10 disposed inside the air vent of the blower.
The wind speed changer 10 of the present embodiment concentrates the wind of the hair dryer to increase the wind speed or widely spreads the wind of the hair dryer to decrease the wind speed, and can blow the hair of the user. In order to dry the hair, the wind of the blower can be widely dispersed to widely blow the hair; in order to perform hairstyle, the air of the blower is concentrated and can be intensively blown to the hairstyle part.
The guide cylindrical portion 14 has a hollow portion 12 having one closed end and the other open end, and the closed end is disposed to face the wind, and the wind flows along the outer peripheral surface. The guide cylindrical portion 14 has a cylindrical shape in the present embodiment as a container shape having one closed end and the other open end, and the hollow portion 12 inside the guide cylindrical portion 14 also has a cylindrical shape.
The blower has a wind generating portion 44 (fig. 6) for generating wind from air sucked from the outside and applying hot wind, and the guide tube portion 14 is disposed at the tip of the wind generating portion 44 such that the closed end of the guide tube portion 14 faces the wind generating portion 44. Accordingly, the wind generated by the wind generating portion 44 blows forward while surrounding the outer peripheral surface of the guide tube portion 14.
The tapered portion 18 of the passage changing portion 28 to be described later is inserted into the hollow portion 12 of the guide cylinder portion 14, and the linear movement of the passage changing portion 28 is guided while the tapered portion 18 advances and retreats.
The duct changing part 28 includes a tapered part 18 and a duct changing pipe 20, one end of the tapered part 18 is inserted into the hollow part 12, passes through the hollow part 12, and is reduced in cross section in the forward direction, and one end of the duct changing pipe 20 is disposed at a distance forward from one end of the tapered part 18 to form an inlet 23 for the wind flowing through the guide tube part 14, and is inserted into and coupled to a part of the tapered part 18.
The tapered portion 18 has a shape having one end inserted into the hollow portion 12, and having a cross section reduced forward while passing through the hollow portion 12. The tapered portion 18 has a conical shape, and the bottom surface may have a sliding portion 16, and the sliding portion 16 is formed in a circular shape and is slidable in contact with the inner surface of the hollow portion 12. The end of the sliding portion 16 may integrally form a tapered portion 18 having a conical shape, and the tapered portion 18 advances or retreats forward through the hollow portion 12 in a state of being inserted into the hollow portion 12 of the guide cylinder portion 14.
The channel changing tube 20 has a tube shape with one end and the other end open, and is coupled to the tapered portion 18 in a state where a part of the tip end portion of the tapered portion 18 is inserted. Referring to fig. 2 and 3, the tapered portion 18 and the channel changing pipe 20 are coupled by the coupling rib 24 in a state where one end of the channel changing pipe 20 is spaced apart from one end of the tapered portion 18 and the tip of the tapered portion 18 is inserted into the channel changing pipe 20. Accordingly, since one end of the tapered portion 18 and one end of the duct changing pipe 20 are spaced apart from each other, an inlet 23 through which air can be introduced is formed, and the air flowing into the inlet 23 passes between the outer circumferential surface of the tapered portion 18 and the inner circumferential surface of the duct changing pipe 20 and is discharged to the other end of the duct changing pipe 20. The other end of the duct changing pipe 20 has a reduced cross-sectional shape compared to the one end, and the wind flowing into the inlet 23 is intensively discharged while passing through the duct changing pipe 20.
The passage changing pipe 20 of the present embodiment has an inner peripheral surface spaced from an outer peripheral surface of the tapered portion 18 to form a passage through which wind moves, and includes a truncated cone portion 22, and the truncated cone portion 22 is formed in a pipe shape whose cross section is reduced in the forward direction to correspond to an outer shape of the tapered portion 18. The channel changing pipe 20 is formed in a truncated cone shape, and further, air is introduced from the larger cross-sectional end of the truncated cone portion 22, flows toward the smaller cross-sectional end, and generates concentrated wind.
The connecting rib 24 is used to couple the tapered portion 18 and the truncated cone portion 22 to each other, and extends from the outer peripheral surface of the tapered portion 18 to couple to the inner surface of the truncated cone portion 22. In the present embodiment, the connecting ribs 24 extend from the tapered portion 18 in a cross shape to join with the truncated cone portion 22.
Referring to fig. 3 and 4, the wind is concentrated or dispersed by the operation of the guide cylinder part 14 and the channel transformation part 28 as follows:
when the inlet 23 of the passage changing part 28 is positioned at the position where the tapered part 18 of the passage changing part 28 is introduced into the hollow part 12 to close the inlet 23 in the state where the tapered part 18 of the passage changing part 28 is inserted into the hollow part 12 of the guide cylinder part 14, the wind passing through the outer circumferential surface of the guide cylinder part 14 cannot flow into the inlet 23 but flows along the outer circumferential surface of the passage changing pipe 20, and the wind is widely dispersed (hereinafter, referred to as "dispersed wind"). On the other hand, when the tapered portion 18 is led out along the hollow portion 12 to open the inlet 23 of the passage changing portion 28, the air flow inlet 23 passing through the outer peripheral surface of the guide tube portion 14 flows along the outer peripheral surface of the tapered portion 18 and the inner peripheral surface of the passage changing pipe 20 while being concentrated (hereinafter, referred to as "concentrated air flow"), and is discharged to the other end of the passage changing pipe 20.
On the other hand, in order to more effectively perform hairstyle by concentrated wind, a nozzle portion 34 having a straight slit 37 is coupled to the other end of the passage changing pipe 20 for discharging concentrated wind. In order to effectively perform hairstyle, it is preferable to discharge the linear wind, whereby the concentrated wind passing through the inside of the passage changing pipe 20 is changed into the linear wind again while passing through the nozzle portion 34.
On the other hand, the wind speed changing device 10 of the present embodiment may further include a cap 36, the cap 36 being formed in a pipe shape, the guide tube portion 14 being disposed inside so that an inner peripheral surface of the cap 36 is spaced from an outer peripheral surface of the guide tube portion 14, and the passage changing pipe 20 being led out from one end of the cap 36 through the lead-out tapered portion 18.
The inner peripheral surface of the cover portion 36 is spaced from the outer peripheral surface of the guide cylinder portion 14, thus providing a flow passage for the dispersed wind passing through the outer peripheral surface of the guide cylinder portion 14. To open and close the inlet 23, the tapered portion 18 enters and exits through the hollow portion 12, thereby introducing or leading out the channel changing tube 20 connected to the tapered portion 18 from one end of the cover portion 36.
Referring to fig. 3, when the channel changing pipe 20 is led out, the discharge of the dispersed wind is closed while one end of the channel changing pipe 20 and one end of the cover 36 face each other; referring to fig. 4, when the duct changing pipe 20 is introduced into the cover 36, one end of the duct changing pipe 20 is spaced inward from one end of the cover 36 and the dispersed air is discharged.
In the present embodiment, the cover 36 is configured such that one end and the other end of the cover 36 are opened and an arch (dome) shape with a reduced front cross section is formed, and when the distributed wind is discharged by introducing the duct changing pipe 20 into the cover 36, the distributed wind is discharged in a concentrated manner, in some cases, while passing through the arch-shaped cover.
On the other hand, the passage changing portion 28 can be moved into and out of the cover portion 36 by moving the guide cylindrical portion 14 into and out of the tapered portion 18. That is, as shown in fig. 3 and 4, the shape is as follows: the guide pipe 38 having a pipe shape extending on the outer periphery of the cover 36 is provided, and the channel changing unit 28 is provided with a slide pipe which is coupled to the channel changing pipe 20, is inserted into the guide pipe 38, is advanced and retracted through the guide pipe 38, and is linearly movable by the guide of the guide pipe 38.
As described in more detail with reference to fig. 1, one end of the duct changing pipe 20 protrudes forward from the discharge part 26, and dispersed wind is discharged through the discharge part 26 due to a gap between the outer circumferential surface of the duct changing pipe 20 and the discharge part 26. The nozzle portion 34 is laterally coupled to one end of the passage changing pipe 20 protruding from the discharge portion 26, and both ends of the nozzle portion 34 are coupled to the discharge portion 26.
On the other hand, the wind speed conversion device of the present embodiment further includes: a tubular guide portion 39 extending forward from the inner bottom portion of the guide cylinder portion 14; an elastic member 40 inserted into the guide portion 39; a guide pin 42 interposed between the elastic member 40 and the inside of the tapered portion 18; the channel changing portion 28 can be easily moved forward and backward by the elastic force of the elastic member 40. That is, when the forward path changing portion 28 is retracted, the tapered portion 18 is introduced into the hollow portion 12 of the guide tube 38, and the guide pin 42 compresses the elastic member 40, thereby generating a reaction force, and the elastic member 40 can apply an elastic force to the guide pin 42 by the reaction force, and further, the forward path changing portion 28 is advanced forward.
When the elastic member 40 is compressed by the retraction of the duct changing part 28 and the duct changing part 28 is engaged by the engaging part 62 (fig. 6) in a state where the elastic member 40 is compressed, the dispersed wind is discharged in a state where the inlet 23 is closed; when the engaging portion 62 is released, the inlet 23 is opened to discharge the exhaust air while the elastic force passage changing portion 28 of the elastic member 40 moves forward.
In order to engage the engaging portion 62, a locking groove 32 is formed in the inner peripheral surface of the slide pipe 30, and the channel changing portion 28 is engaged while the engaging portion 62 is inserted into the locking groove 32.
